ABSTRACT:
A magnifying glass is supported by a first ball joint connection to a housing suspended by a second ball joint connection from the upper portion of a clamping means. The clamping means is provided at its lowermost extremity with opposed elongated jaws adapted to grip an elongated object such as a pencil. Spring means associated with said clamping means urge said jaws together. A stabilizing post attached to the upper extremity of said clamping means is adapted to rest atop the user's thumb to provide greater steadiness of the implement and attached magnifying glass device.
